A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...
XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...
According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint ...
If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...
Gravitational lensing often evokes images of a cosmic funhouse mirror: duplicated galaxies, dramatic arcs and distorted shapes. But the web-like, large-scale structure throughout the universe also ...
Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height ...
Any object lifted above the ground has gravitational potential energy (\(E_{p}\) or GPE). The amount of gravitational potential energy an object has on Earth depends on its: mass; height above the ...
A new study in Physical Review Letters has used atomic clocks to study relativistic effects in interacting quantum systems.
Though astrophysicists think that a high-energy astrophysical process is the likely source of FRBs, they aren't certain how they're generated. Researchers used gravitational waves (GWs ...
Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping.
